to abandon, and timing options.

4. Decision trees represent an approach for valuing projects with these hidden, or real, options.

Concept Questions

1. Forecasting Risk What is forecasting risk? In general, would the degree of forecasting risk be

greater for a new product or a cost-cutting proposal? Why?

2. Sensitivity Analysis and Scenario Analysis What is the essential difference between

sensitivity analysis and scenario analysis?

3. Marginal Cash Flows A coworker claims that looking at all this marginal this and incremental

that is just a bunch of nonsense, and states, “Listen, if our average revenue doesn’t exceed our average cost, then we will have a negative cash flow, and we will go broke!” How do you respond?

4. Break-Even Point As a shareholder of a firm that is contemplating a new project, would you

be more concerned with the accounting break-even point, the cash break-even point (the point at which operating cash flow is zero), or the financial break-even point? Why?

5. Break-Even Point Assume a firm is considering a new project that requires an initial

investment and has equal sales and costs over its life. Will the project reach the accounting, cash, or financial break-even point first? Which will it reach next? Last? Will this order always apply?

6. Real Options Why does traditional NPV analysis tend to underestimate the true value of a

capital budgeting project?

7. Real Options The Mango Republic has just liberalized its markets and is now permitting

foreign investors. Tesla Manufacturing has analyzed starting a project in the country and has determined that the project has a negative NPV. Why might the company go ahead with the project? What type of option is most likely to add value to this project?

8. Sensitivity Analysis and Breakeven How does sensitivity analysis interact with break-even

analysis?

9. Option to Wait An option can often have more than one source of value. Consider a logging

company. The company can log the timber today or wait another year (or more) to log the timber.

What advantages would waiting one year potentially have?

10. Project Analysis You are discussing a project analysis with a coworker. The project involves

real options, such as expanding the project if successful, or abandoning the project if it fails. Your coworker makes the following statement: “This analysis is ridiculous. We looked at expanding or abandoning the project in two years, but there are many other options we should consider. For example, we could expand in one year, and expand further in two years. Or we could expand in one year, and abandon the project in two years. There are too many options for us to examine.

Because of this, anything this analysis would give us is worthless.” How would you evaluate this statement? Considering that with any capital budgeting project there are an infinite number of real options, when do you stop the option analysis on an individual project?

Questions and Problems: connect?

BASIC (Questions 1–10)

1. Sensitivity Analysis and Break-Even Point We are evaluating a project that costs

$724,000, has an eight-year life, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 75,000 units per year. Price per unit is $39, variable cost per unit is $23, and fixed costs are $850,000 per year. The tax rate is 35 percent, and we require a 15 percent return on this project.

1. Calculate the accounting break-even point.

2. Calculate the base-case cash flow and NPV. What is the sensitivity of NPV to changes in

the sales figure? Explain what your answer tells you about a 500-unit decrease in projected sales.

3. What is the sensitivity of OCF to changes in the variable cost figure? Explain what your

answer tells you about a $1 decrease in estimated variable costs.

2. Scenario Analysis In the previous problem, suppose the projections given for price, quantity,

variable costs, and fixed costs are all accurate to within ±10 percent. Calculate the best-case and worst-case NPV figures.

3. Calculating Breakeven In each of the following cases, find the unknown variable. Ignore

taxes.

4. Financial Breakeven L.J.’s Toys Inc. just purchased a $250,000 machine to produce toy cars.

The machine will be fully depreciated by the straight-line method over its five-year economic life.

Each toy sells for $25. The variable cost per toy is $6, and the firm incurs fixed costs of $360,000 each year. The corporate tax rate for the company is 34 percent. The appropriate discount rate is

12 percent. What is the financial break-even point for the project?

5. Option to Wait Your company is deciding whether to invest in a new machine. The new

machine will increase cash flow by $340,000 per year. You believe the technology used in the machine has a 10-year life; in other words, no matter when you purchase the machine, it will be obsolete 10 years from today. The machine is currently priced at $1,800,000. The cost of the machine will decline by $130,000 per year until it reaches $1,150,000, where it will remain. If your required return is 12 percent, should you purchase the machine? If so, when should you purchase it?

6. Decision Trees Ang Electronics, Inc., has developed a new DVDR. If the DVDR is successful,

the present value of the payoff (when the product is brought to market) is $22 million. If the DVDR fails, the present value of the payoff is $9 million. If the product goes directly to market, there is a

50 percent chance of success. Alternatively, Ang can delay the launch by one year and spend $1.5

million to test market the DVDR. Test marketing would allow the firm to improve the product and increase the probability of success to 80 percent. The appropriate discount rate is 11 percent.

Should the firm conduct test marketing?

7. Decision Trees The manager for a growing firm is considering the launch of a new product. If

the product goes directly to market, there is a 50 percent chance of success. For $135,000 the manager can conduct a focus group that will increase the product’s chance of success to 65 percent. Alternatively, the manager has the option to pay a consulting firm $400,000 to research the market and refine the product. The consulting firm successfully launches new products 85 percent of the time. If the firm successfully launches the product, the payoff will be $1.5 million. If the product is a failure, the NPV is zero. Which action will result in the highest expected payoff to the firm?

8. Decision Trees B&B has a new baby powder ready to market. If the firm goes directly to the

market with the product, there is only a 55 percent chance of success. However, the firm can conduct customer segment research, which will take a year and cost $1.8 million. By going through research, B&B will be able to better target potential customers and will increase the probability of success to 70 percent. If successful, the baby powder will bring a present value profit (at time of initial selling) of $28 million. If unsuccessful, the present value payoff is only $4 million. Should the firm conduct customer segment research or go directly to market? The appropriate discount rate is

15 percent.

9. Financial Break-Even Analysis You are considering investing in a company that cultivates

abalone for sale to local restaurants. Use the following information:

The discount rate for the company is 15 percent, the initial investment in equipment is $360,000, and the project’s economic life is seven years. Assume the equipment is depreciated on a straight-line basis over the project’s life.

1. What is the accounting break-even level for the project?

2. What is the financial break-even level for the project?

10. Financial Breakeven Niko has purchased a brand new machine to produce its High Flight line

of shoes. The machine has an economic life of five years. The depreciation schedule for the machine is straight-line with no salvage value. The machine costs $390,000. The sales price per pair of shoes is $60, while the variable cost is $14. $185,000 of fixed costs per year are attributed to the machine. Assume that the corporate tax rate is 34 percent and the appropriate discount rate is 8 percent. What is the financial break-even point?

INTERMEDIATE (Questions 11–25)

11. Break-Even Intuition Consider a project with a required return of R percent that costs $I and

will last for N years. The project uses straight-line depreciation to zero over the N-year life; there are neither salvage value nor net working capital requirements.

1. At the accounting break-even level of output, what is the IRR of this project? The payback

period? The NPV?

2. At the cash break-even level of output, what is the IRR of this project? The payback

period? The NPV?

3. At the financial break-even level of output, what is the IRR of this project? The payback

period? The NPV?

12. Sensitivity Analysis Consider a four-year project with the following information: Initial fixed

asset investment = $380,000; straight-line depreciation to zero over the four-year life; zero salvage value; price = $54; variable costs = $42; fixed costs = $185,000; quantity sold = 90,000 units; tax rate = 34 percent. How sensitive is OCF to changes in quantity sold?

13. Project Analysis You are considering a new product launch. The project will cost $960,000,

have a four-year life, and have no salvage value; depreciation is straight-line to zero. Sales are projected at 240 units per year; price per unit will be $25,000; variable cost per unit will be $19,500; and fixed costs will be $830,000 per year. The required return on the project is 15 percent, and the relevant tax rate is 35 percent.

1. Based on your experience, you think the unit sales, variable cost, and fixed cost

projections given here are probably accurate to within ±10 percent. What are the upper and lower bounds for these projections? What is the base-case NPV? What are the best-case and worst-case scenarios?

2. Evaluate the sensitivity of your base-case NPV to changes in fixed costs.

3. What is the accounting break-even level of output for this project?

14. Project Analysis McGilla Golf has decided to sell a new line of golf clubs. The clubs will sell for

$750 per set and have a variable cost of $390 per set. The company has spent $150,000 for a marketing study that determined the company will sell 55,000 sets per year for seven years. The marketing study also determined that the company will lose sales of 12,000 sets of its high-priced clubs. The high-priced clubs sell at $1,100 and have variable costs of $620. The company will also increase sales of its cheap clubs by 15,000 sets. The cheap clubs sell for $400 and have variable costs of $210 per set. The fixed costs each year will be $8,100,000. The company has also spent $1,000,000 on research and development for the new clubs. The plant and equipment required will cost $18,900,000 and will be depreciated on a straight-line basis. The new clubs will also require an increase in net working capital of $1,400,000 that will be returned at the end of the project. The tax rate is 40 percent, and the cost of capital is 14 percent. Calculate the payback period, the NPV, and the IRR.

15. Scenario Analysis In the previous problem, you feel that the values are accurate to within

only ±10 percent. What are the best-case and worst-case NPVs? (Hint: The price and variable costs for the two existing sets of clubs are known with certainty; only the sales gained or lost are uncertain.)

16. Sensitivity Analysis McGilla Golf would like to know the sensitivity of NPV to changes in the

price of the new clubs and the quantity of new clubs sold. What is the sensitivity of the NPV to each of these variables?

17. Abandonment Value We are examining a new project. We expect to sell 9,000 units per year

at $50 net cash flow apiece for the next 10 years. In other words, the annual operating cash flow is projected to be $50 × 9,000 = $450,000. The relevant discount rate is 16 percent, and the initial investment required is $1,900,000.

1. What is the base-case NPV?

2. After the first year, the project can be dismantled and sold for $1,300,000. If expected

sales are revised based on the first year’s performance, when would it make sense to abandon the investment? In other words, at what level of expected sales would it make sense to abandon the project?

3. Explain how the $1,300,000 abandonment value can be viewed as the opportunity cost of

keeping the project in one year.

18. Abandonment In the previous problem, suppose you think it is likely that expected sales will

be revised upward to 11,000 units if the first year is a success and revised downward to 4,000 units if the first year is not a success.

1. If success and failure are equally likely, what is the NPV of the project? Consider the

possibility of abandonment in answering.

2. What is the value of the option to abandon?

19. Abandonment and Expansion In the previous problem, suppose the scale of the project can

be doubled in one year in the sense that twice as many units can be produced and sold. Naturally, expansion would be desirable only if the project were a success. This implies that if the project is a success, projected sales after expansion will be 22,000. Again assuming that success and failure are equally likely, what is the NPV of the project? Note that abandonment is still an option if the project is a failure. What is the value of the option to expand?

20. Break-Even Analysis Your buddy comes to you with a sure-fire way to make some quick

money and help pay off your student loans. His idea is to sell T-shirts with the words “I get” on them. “You get it?” He says, “You see all those bumper stickers and T-shirts that say ‘got milk’ or ‘got surf.’ So this says, ‘I get.’ It’s funny! All we have to do is buy a used silk screen press for $3,200 and we are in business!” Assume there are no fixed costs, and you depreciate the $3,200 in the first period. Taxes are 30 percent.

1. What is the accounting break-even point if each shirt costs $7 to make and you can sell

them for $10 apiece?

Now assume one year has passed and you have sold 5,000 shirts! You find out that the Dairy Farmers of America have copyrighted the “got milk” slogan and are requiring you to pay $12,000 to continue operations. You expect this craze will last for another three years and that your discount rate is 12 percent.

2. What is the financial break-even point for your enterprise now?

21. Decision Trees Young screenwriter Carl Draper has just finished his first script. It has action,

drama, and humor, and he thinks it will be a blockbuster. He takes the script to every motion picture studio in town and tries to sell it but to no avail. Finally, ACME studios offers to buy the script for either (a) $12,000 or (b) 1 percent of the movie’s profits. There are two decisions the studio will have to make. First is to decide if the script is good or bad, and second if the movie is good or bad. First, there is a 90 percent chance that the script is bad. If it is bad, the studio does nothing more and throws the script out. If the script is good, they will shoot the movie. After the movie is shot, the studio will review it, and there is a 70 percent chance that the movie is bad. If the movie is bad, the movie will not be promoted and will not turn a profit. If the movie is good, the studio will promote heavily; the average profit for this type of movie is $20 million. Carl rejects the $12,000 and says he wants the 1 percent of profits. Was this a good decision by Carl?

22. Option to Wait Hickock Mining is evaluating when to open a gold mine. The mine has 60,000

ounces of gold left that can be mined, and mining operations will produce 7,500 ounces per year.

The required return on the gold mine is 12 percent, and it will cost $14 million to open the mine.

When the mine is opened, the company will sign a contract that will guarantee the price of gold for the remaining life of the mine. If the mine is opened today, each ounce of gold will generate an aftertax cash flow of $450 per ounce. If the company waits one year, there is a 60 percent probability that the contract price will generate an aftertax cash flow of $500 per ounce and a 40 percent probability that the aftertax cash flow will be $410 per ounce. What is the value of the option to wait?

23. Abandonment Decisions Allied Products, Inc., is considering a new product launch. The firm

expects to have an annual operating cash flow of $22 million for the next 10 years. Allied Products uses a discount rate of 19 percent for new product launches. The initial investment is $84 million.

Assume that the project has no salvage value at the end of its economic life.

1. What is the NPV of the new product?

2. After the first year, the project can be dismantled and sold for $30 million. If the

estimates of remaining cash flows are revised based on the first year’s experience, at what level of expected cash flows does it make sense to abandon the project?

24. Expansion Decisions Applied Nanotech is thinking about introducing a new surface cleaning

machine. The marketing department has come up with the estimate that Applied Nanotech can sell

15 units per year at $410,000 net cash flow per unit for the next five years. The engineering

department has come up with the estimate that developing the machine will take a $17 million initial investment. The finance department has estimated that a 25 percent discount rate should be

used.

1. What is the base-case NPV?

2. If unsuccessful, after the first year the project can be dismantled and will have an aftertax

salvage value of $11 million. Also, after the first year, expected cash flows will be revised up to 20 units per year or to 0 units, with equal probability. What is the revised NPV?

25. Scenario Analysis You are the financial analyst for a tennis racket manufacturer. The

company is considering using a graphitelike material in its tennis rackets. The company has estimated the information in the following table about the market for a racket with the new material. The company expects to sell the racket for six years. The equipment required for the project has no salvage value. The required return for projects of this type is 13 percent, and the company has a 40 percent tax rate. Should you recommend the project?

CHALLENGE (Questions 26–30)

26. Scenario Analysis Consider a project to supply Detroit with 55,000 tons of machine screws

annually for automobile production. You will need an initial $1,700,000 investment in threading equipment to get the project started; the project will last for five years. The accounting department estimates that annual fixed costs will be $520,000 and that variable costs should be $220 per ton;

accounting will depreciate the initial fixed asset investment straight-line to zero over the five-year project life. It also estimates a salvage value of $300,000 after dismantling costs. The marketing department estimates that the automakers will let the contract at a selling price of $245 per ton.

The engineering department estimates you will need an initial net working capital investment of $600,000. You require a 13 percent return and face a marginal tax rate of 38 percent on this project.

1. What is the estimated OCF for this project? The NPV? Should you pursue this project?

2. Suppose you believe that the accounting department’s initial cost and salvage value

projections are accurate only to within ±15 percent; the marketing department’s price estimate is accurate only to within ±10 percent; and the engineering department’s net working capital estimate is accurate only to within ±5 percent. What is your worst-case scenario for this project? Your best-case scenario? Do you still want to pursue the project? 27. Sensitivity Analysis In Problem 26, suppose you’re confident about your own projections, but

you’re a little unsure about Detroit’s actual machine screw requirements. What is the sensitivity of the project OCF to changes in the quantity supplied? What about the sensitivity of NPV to changes in quantity supplied? Given the sensitivity number you calculated, is there some minimum level of output below which you wouldn’t want to operate? Why?

28. Abandonment Decisions Consider the following project for Hand Clapper, Inc. The company

is considering a four-year project to manufacture clap-command garage door openers. This project requires an initial investment of $10 million that will be depreciated straight-line to zero over the project’s life. An initial investment in net working capital of $1.3 million is required to support spare parts inventory; this cost is fully recoverable whenever the project ends. The company believes it can generate $7.35 million in pretax revenues with $2.4 million in total pretax operating costs. The tax rate is 38 percent, and the discount rate is 16 percent. The market value of the equipment over the life of the project is as follows:

Lumber is sold by the company for its “pond value.” Pond value is the amount a mill will pay for a log delivered to the mill location. The price paid for logs delivered to a mill is quoted in dollars per thousands of board feet (MBF), and the price depends on the grade of the logs. The forest Bunyan Lumber is evaluating was planted by the company 20 years ago and is made up entirely of Douglas fir trees. The table here shows the current price per MBF for the three grades of timber the company feels will come from the stand:

Steve believes that the pond value of lumber will increase at the inflation rate. The company is planning to thin the forest today, and it expects to realize a positive cash flow of $1,000 per acre from thinning. The thinning is done to increase the growth rate of the remaining trees, and it is always done 20 years following a planting.

The major decision the company faces is when to log the forest. When the company logs the forest, it will immediately replant saplings, which will allow for a future harvest. The longer the forest is allowed to grow, the larger the harvest becomes per acre. Additionally, an older forest has a higher grade of timber. Steve has compiled the following table with the expected harvest per acre in thousands of board feet, along with the breakdown of the timber grades:

The company expects to lose 5 percent of the timber it cuts due to defects and breakage.

The forest will be clear-cut when the company harvests the timber. This method of harvesting allows for faster growth of replanted trees. All of the harvesting, processing, replanting, and transportation are to be handled by subcontractors hired by Bunyan Lumber. The cost of the logging is expected to be $140 per MBF. A road system has to be constructed and is expected to cost $50 per MBF on average. Sales preparation and administrative costs, excluding office overhead costs, are expected to be $18 per MBF.

As soon as the harvesting is complete, the company will reforest the land. Reforesting costs include the following:

All costs are expected to increase at the inflation rate.

Assume all cash flows occur at the year of harvest. For example, if the company begins harvesting the timber 20 years from today, the cash flow from the harvest will be received 20 years from today. When the company logs the land, it will immediately replant the land with new saplings. The harvest period chosen will be repeated for the foreseeable future. The company’s nominal required return is 10 percent, and the inflation rate is expected to be 3.7 percent per year. Bunyan Lumber has a 35 percent tax rate.

Clear-cutting is a controversial method of forest management. To obtain the necessary permits, Bunyan Lumber has agreed to contribute to a conservation fund every time it harvests the lumber. If the company harvested the forest today, the required contribution would be $250,000. The company has agreed that the required contribution will grow by 3.2 percent per year. When should the company harvest the forest?

罗斯《公司理财》第9版精要版英文原书课后部分章节答案详细? 1 / 17 CH5 11，13，18，19，20 11. To find the PV of a lump sum, we use: PV = FV / (1 + r) t PV = $1,000,000 / (1.10) 80 = $488.19 13. To answer this question, we can use either the FV or the PV formula. Both will give the same answer since they are the inverse of each other. We will use the FV formula, that is: FV = PV(1 + r) t Solving for r, we get: r = (FV / PV) 1 / t –1 r = ($1,260,000 / $150) 1/11 2 – 1 = .0840 or 8.40% To find the FV of the first prize, we use: FV = PV(1 + r) t FV = $1,260,000(1.0840) 3 3 = $18,056,409.9 4 18. To find the FV of a lump sum, we use: FV = PV(1 + r) t FV = $4,000(1.11) 4 5 = $438,120.97 FV = $4,000(1.11) 35 = $154,299.40 Better start early! 19. We need to find the FV of a lump sum. However, the money will only be invested for six years, so the number of periods is six. FV = PV(1 + r) t FV = $20,000(1.084) 6 = $32,449.33 20. To answer this question, we can use either the FV or the PV formula. Both will give the same answer since they are the inverse of each other. We will use the FV formula, that is: FV = PV(1 + r) t Solving for t, we get: t = ln(FV / PV) / ln(1 + r) t = ln($75,000 / $10,000) / ln(1.11) = 19.31 So, the money must be invested for 19.31 years. However, you will not receive the money for another two years. From now, you’ll wait: 2 years + 19.31 years = 21.31 years CH6 16，24，27，42，58 16. For this problem, we simply need to find the FV of a lump sum using the equation: FV = PV(1 + r) t 2 / 1 7 It is important to note that compounding occurs semiannually. To account for this, we will divide the interest rate by two (the number of compounding periods in a year), and multiply the number of periods by two. Doing so, we get: FV = $2,100[1 + (.084/2)] 34 = $8,505.93 24. This problem requires us to find the FVA. The equation to find the FVA is: FV A = C{[(1 + r) t – 1] / r} FV A = $300[{[1 + (.10/12) ] 360 – 1} / (.10/12)] = $678,146.3 8 27. The cash flows are annual and the compounding period is quarterly, so we need to calculate the EAR to make the interest rate comparable with the timing of the cash flows. Using the equation for the EAR, we get: EAR = [1 + (APR / m)] m – 1 EAR = [1 + (.11/4)] 4 – 1 = .1146 or 11.46% And now we use the EAR to find the PV of each cash flow as a lump sum and add them together: PV = $725 / 1.1146 + $980 / 1.1146 2 + $1,360 / 1.1146 4 = $2,320.36 42. The amount of principal paid on the loan is the PV of the monthly payments you make. So, the present value of the $1,150 monthly payments is: PVA = $1,150[(1 – {1 / [1 + (.0635/12)]} 360 ) / (.0635/12)] = $184,817.42 The monthly payments of $1,150 will amount to a principal payment of $184,817.42. The amount of principal you will still owe is: $240,000 – 184,817.42 = $55,182.58 This remaining principal amount will increase at the interest rate on the loan until the end of the loan period. So the balloon payment in 30 years, which is the FV of the remaining principal will be: Balloon payment = $55,182.58[1 + (.0635/12)] 360 = $368,936.54 58. To answer this question, we should find the PV of both options, and compare them. Since we are purchasing the car, the lowest PV is the best option. The PV of the leasing is simply the PV of the lease payments, plus the $99. The interest rate we would use for the leasing option is the same as the interest rate of the loan. The PV of leasing is: PV = $9 9 + $450{1 –[1 / (1 + .07/12) 12(3) ]} / (.07/12) = $14,672.91 The PV of purchasing the car is the current price of the car minus the PV of the resale price. The PV of the resale price is : PV = $23,000 / [1 + (.07/12)] 12(3) = $18,654.82 The PV of the decision to purchase is: $32,000 – 18,654.82 = $13,345.18 3 / 17 In this case, it is cheaper to buy the car than leasing it since the PV of the purchase cash flows is lower. To find the breakeven resale price, we need to find the resale price that makes the PV of the two options the same.

第三章财务报表分析与长期财务规划 1.由于不同行业的公司在财务比率上存在很大的差异，财务比率本身提供的信息有限，分析公司的财务比率有两种基本方法：时间趋势分析法和同类公司分析。为什么这些方法会有用呢？每种方法能够告诉你哪些关于公司财务健康状况的信息？ 答：时间趋势分析描绘了公司财务状况随时间而变化的图景。通过公司本身的跨期比较分析，财务经理可以评价公司的经营、融资或投资活动的某些方面是否已经发生了变化。同类公司比较分析涉及到将某一特定公司的财务比率和经营绩效与同一行业或业务相同的其他公司进行比较。通过同类公司比较分析，财务经理可以评价公司的经营、融资或投资活动的某些方面是否越出常规，从而为调整这些比率采取恰当的行动提供指南，如果这种调整合适的话。两种方法都从财务的视角研究一个公司究竟有什么不同，但两种方法都不能告诉我们这种不同是积极正面的还是消极负面的。例如，假设一个公司的流动比率是随时间而提高，这可能意味着该公司在过去一直面临流动性问题，一直在纠正这些问题；或者它也可能意味着该公司已经在管理流动资产和负债方面变得更低效。同类公司比较分析中也存在类似的争论。一个公司的流动比率低于同类公司，也许是它在管理流动资产和负债方面更具效率，也可能是它面临流动性问题。没有哪种方法告诉我们某个比率是好还是坏。两种方法只是表明有些东西存在差异，并告诉我们去哪里寻找。 2.所谓的“同店销售”是像沃尔玛和希尔斯之类的十分分散的公司的

一项重要指标，顾名思义，分析同店销售就是比较同样的店铺或餐馆在两个不同的时间点上的销售额。为什么公司总是关注同店销售而不是总销售？ 答：如果一家公司通过开设新店来不断增长，那么可以推测其总收入将上升。比较两个不同时点的总销售额可能会误导。同店销售方法只看在特定时期开设的店铺的销售额控制了这一误差。 3.为什么多数长期财务计划都从销售预测开始？或者说，为什么未来销售额是关键？ 答：理由是，最终，消费是商业背后的驱动力。一个企业的资产、雇员，事实上，几乎企业经营和融资的所有方面都是直接或间接地支持销售。换种说法，一个企业对资本资产、雇员、存货以及融资的未来需求都由它的未来销售所决定。 4.本章利用Rosengarten公司说明EFN的计算，Rosengarten的ROE 约为7.3%，利润再投资率约为67%，如果你为Rosengarten计算可持续增长率，会发现它只有 5.14%，而我们在计算EFN时所使用的增长率为25%，这可能吗？（提示：有可能。如何实现？） 答：可持续增长公式的两个假设是，公司并不想出售新的股票，以及财务政策是固定的。如果公司增加外部股权，或提高其债务权益比率，它的增长速度可以比可持续增长率更高。当然，如果公司改变其股利政策，提高留成比例，或其总资产周转率提高，它的增长速度也可以快于它的销售净利率提高的速度。 5. Broslofski公司每年都维持一个正的留存比率，并保持负债权益比

罗斯《公司理财》第9版笔记和课后习题(含考研真题)详解[视频详解](风险、资本成本和资本预算)【圣才

罗斯《公司理财》第9版笔记和课后习题（含考研真题）详解[视频详解] 第13章风险、资本成本和资本预算[视频讲解] 13.1复习笔记 运用净现值法，按无风险利率对现金流量折现，可以准确评价无风险现金流量。然而，现实中的绝大多数未来现金流是有风险的，这就要求有一种能对有风险现金流进行折现的方法。确定风险项目净现值所用的折现率可根据资本资产定价模型CAPM（或套利模型APT）来计算。如果某无负债企业要评价一个有风险项目，可以运用证券市场线SML来确定项目所要求的收益率r s，r s也称为权益资本成本。 当企业既有债务融资又有权益融资时，所用的折现率应是项目的综合资本成本，即债务资本成本和权益资本成本的加权平均。 联系企业的风险贴现率与资本市场要求的收益率的原理在于如下一个简单资本预算原则：企业多余的现金，可以立即派发股利，投资者收到股利自己进行投资，也可以用于投资项目产生未来的现金流发放股利。从股东利益出发，股东会在自己投资和企业投资中选择期望收益率较高的一个。只有当项目的期望收益率大于风险水平相当的金融资产的期望收益率时，项目才可行。因此项目的折现率应该等于同样风险水平的金融资产的期望收益率。这也说明了资本市场价格信号作用。 1．权益资本成本 从企业的角度来看，权益资本成本就是其期望收益率，若用CAPM模型，股票的期望收益率为：

其中，R F是无风险利率，是市场组合的期望收益率与无风险利率之差，也称为期望超额市场收益率或市场风险溢价。 要估计企业权益资本成本，需要知道以下三个变量：①无风险利率；②市场风险溢价； ③公司的贝塔系数。 根据权益资本成本计算企业项目的贴现率需要有两个重要假设：①新项目的贝塔风险与企业风险相同；②企业无债务融资。 2．贝塔的估计 估算公司贝塔值的基本方法是利用T个观测值按照如下公式估计： 估算贝塔值可能存在以下问题：①贝塔可能随时间的推移而发生变化；②样本容量可能太小；③贝塔受财务杠杆和经营风险变化的影响。 可以通过如下途径解决上述问题：①第1个和第2个问题可通过采用更加复杂的统计技术加以解决；②根据财务风险和经营风险的变化对贝塔作相应的调整，有助于解决第3个问题；③注意同行业类似企业的平均β估计值。 根据企业自身历史数据来估算企业贝塔系数是一种常用方法，也有人认为运用整个行业的贝塔系数可以更好地估算企业的贝塔系数。有时两者计算的结果差异很大。总的来说，可以遵循下列原则：如果认为企业的经营与所在行业其他企业的经营十分类似，用行业贝塔降低估计误差。如果认为企业的经营与行业内其他企业的经营有着根本性差别，则应选择企业的贝塔。 3．贝塔的确定 前面介绍的回归分析方法估算贝塔并未阐明贝塔是由哪些因素决定的。主要存在以下三个因素：收入的周期性、经营杠杆和财务杠杆。

第一章 1.在所有权形式的公司中,股东是公司的所有者。股东选举公司的董事会,董事会任命该公司的管理层。企业的所有权和控制权分离的组织形式是导致的代理关系存在的主要原因。管理者可能追求自身或别人的利益最大化,而不是股东的利益最大化。在这种环境下,他们可能因为目标不一致而存在代理问题。 2.非营利公司经常追求社会或政治任务等各种目标。非营利公司财务管理的目标是获取并有效使用资金以最大限度地实现组织的社会使命。 3.这句话是不正确的。管理者实施财务管理的目标就是最大化现有股票的每股价值，当前的股票价值反映了短期和长期的风险、时间以及未来现金流量。 4.有两种结论。一种极端,在市场经济中所有的东西都被定价。因此所有目标都有一个最优水平，包括避免不道德或非法的行为，股票价值最大化。另一种极端,我们可以认为这是非经济现象,最好的处理方式是通过政治手段。一个经典的思考问题给出了这种争论的答案:公司估计提高某种产品安全性的成本是30美元万。然而,该公司认为提高产品的安全性只会节省20美元万。请问公司应该怎么做呢?” 5.财务管理的目标都是相同的,但实现目标的最好方式可能是不同的,因为不同的国家有不同的社会、政治环境和经济制度。 6.管理层的目标是最大化股东现有股票的每股价值。如果管理层认为能提高公司利润，使股价超过35美元,那么他们应该展开对恶意收购的斗争。如果管理层认为该投标人或其它未知的投标人将支付超过每股35美元的价格收购公司,那么他们也应该展开斗争。然而,如果管理层不能增加企业的价值,并且没有其他更高的投标价格,那么管理层不是在为股东的最大化权益行事。现在的管理层经常在公司面临这些恶意收购的情况时迷失自己的方向。 7.其他国家的代理问题并不严重,主要取决于其他国家的私人投资者占比重较小。较少的私人投资者能减少不同的企业目标。高比重的机构所有权导致高学历的股东和管理层讨论决策风险项目。此外,机构投资者比私人投资者可以根据自己的资源和经验更好地对管理层实施有效的监督机制。 8.大型金融机构成为股票的主要持有者可能减少美国公司的代理问题，形成更有效率的公司控制权市场。但也不一定能。如果共同基金或者退休基金的管理层并不关心的投资者的利益，代理问题可能仍然存在,甚至有可能增加基金和投资者之间的代理问题。

第十章：风险与收益：市场历史的启示 1. 因为公司的表现具有不可预见性。 2. 投资者很容易看到最坏的投资结果，但是确很难预测到。 3. 不是，股票具有更高的风险，一些投资者属于风险规避者，他们认为这点额外的报酬率还不至于吸引他们付出更高风险的代价。 4. 股票市场与赌博是不同的，它实际是个零和市场，所有人都可能赢。而且投机者带给市场更高的流动性，有利于市场效率。 5. 在80 年代初是最高的，因为伴随着高通胀和费雪效应。 6. 有可能，当投资风险资产报酬非常低，而无风险资产报酬非常高，或者同时出现这两种现象时就会发生这样的情况。 7. 相同，假设两公司2 年前股票价格都为P0，则两年后G 公司股票价格为 1.1*0.9* P0，而S 公司股票价格为0.9*1.1 P0，所以两个公司两年后的股价是一样的。 8. 不相同，Lake Minerals 2年后股票价格= 100(1.10)(1.10) = $121.00 而SmallTown Furniture 2年后股票价格= 100(1.25)(.95) = $118.75 9. 算数平均收益率仅仅是对所有收益率简单加总平均，它没有考虑到所有收益率组合的效果，而几何平均收益率考虑到了收益率组合的效果，所以后者比较重要。 10. 不管是否考虑通货膨胀因素，其风险溢价没有变化，因为风险溢价是风险资产收益率与无风险资产收益率的差额，若这两者都考虑到通货膨胀的因素，其差额仍然是相互抵消的。而在考虑税收后收益率就会降低，因为税后收益会降低。 11. R = [($104 – 92) + 1.45] / $92 = .1462 or 14.62% 12. Dividend yield = $1.45 / $92 = .0158 or 1.58% Capital gains yield = ($104 – 92) / $92 = .1304 or 13.04% 13. R = [($81 – 92) + 1.45] / $92 = –.1038 or –10.38% Dividend yield = $1.45 / $92 = .0158 or 1.58% Capital gains yield = ($81 – 92) / $92 = –.1196 or –11.96% 14.

第17章 财务杠杆和资本结构政策 ◆本章复习与自测题 17.1 EBIT和EPS 假设BDJ公司已经决定进行一项资本重组，它涉及到将现有的8 000万美元债务增加到12 500万美元。债务的利率是9%，并且预期不会改变。公司目前有1 000万股流通在外，每股价格是45美元。如果预期重组可以提高ROE，那么，BDJ的管理当局必定预期EBIT至少达到什么水平？解答时不考虑税。 17.2 MM第二定理（无税） Habitat公司的WACC是16%，债务成本是13%。如果Habitat的债务权益率是2，它的权益资本成本是多少？解答时不考虑税。 17.3 MM第一定理（有公司税） Gypco公司预期永远都有每年10 000美元的EBIT。Gypco可以以7%的利率借款。假设Gypco目前没有债务，它的权益成本是17%。如果公司的税率是35%，公司的价值是多少？如果Gypco借入15 000美元，并用它来回购股票，公司的价值是多少？ ◆本章复习与自测题解答 17.1 要解答这个问题，我们可以计算临界EBIT。在超过这一点的任何EBIT上，提高财务杠杆都将提高EPS。在原有 的资本结构下，利息费用是8 000万美元×0.09 = 720万美元。因为有1 000万股股票，因此，不考虑税，EPS为：（EBIT-720万美元)/1 000万。 在新的资本结构下，利息费用是：12 500万美元×0.09 = 1 125万美元。并且，债务增加了4 500万美元。这个金额足够买回4 500万美元/45 = 100万股股票，剩下900万股流通在外。因此，EPS是：（EBIT -1 125万美元)/900万。 既然我们知道如何计算这两种情况下的EPS。我们假定它们彼此相等，求出临界EBIT： (EBIT -720万美元)/1 000万= (EBIT-1 125万美元)/900万 (EBIT -720万美元) = 1.11×(EBIT-1 125万美元) EBIT = 4 770万美元 可以验证，在两种情况下，当EBIT是4 770万美元时，EPS都是4.05美元。 17.2 根据MM第二定理（无税），权益成本是： R E = R A + (R A -R D )×(D/E）= 16% + (16% -13%)×2 = 22% 17.3 在没有公司税的情况下，Gypco的WACC是17%。这也是不利用杠杆的公司的资本成本。税后现金流量是：10 000美元×(1-0.35) = 6 500美元，因此，价值就是：V U = 6 500美元/0.17 = 38 235美元。 发行债务之后，Gypco的价值将是原来的38 235美元加上税盾的现值T C ×D，也就是0.35×15 000美元= 5 250美元。因

第六章：投资决策 1.机会成本是指进行一项投资时放弃另一项投资所承担的成本。选择投资和放弃投资之间的收益差是可能获取收益的成本。 2. （1）新的投资项目所来的公司其他产品的销售下滑属于副效应中的侵蚀效应，应被归为增量现金流。 （2）投入建造的机器和厂房属于新生产线的成本，应被归为增量现金流。（3）过去3 年发生的和新项目相关的研发费用属于沉没成本，不应被归为增量现金流。 （4）尽管折旧不是现金支出，对现金流量产生直接影响，但它会减少公司的净收入，并且减低公司的税收，因此应被归为增量现金流。 （5）公司发不发放股利与投不投资某一项目的决定无关，因此不应被归为增量现金流。 （6）厂房和机器设备的销售收入是一笔现金流入，因此应被归为增量现金流。（7）需要支付的员工薪水与医疗保险费用应被包括在项目成本里，因此应被归为增量现金流。 3. 第一项因为会产生机会成本，所以会产生增量现金流；第二项因为会产生副效应中的侵蚀效应，所以会会产生增量现金流；第三项属于沉没成本，不会 产生增量现金流。 4. 为了避免税收，公司可能会选择MACRS，因为该折旧法在早期有更大的折旧额，这样可以减免赋税，并且没有任何现金流方面的影响。但需要注意的是直线折旧法与MACRS 的选择只是时间价值的问题，两者的折旧是相等的，只是时间不同。 5. 这只是一个简单的假设。因为流动负债可以全部付清，流动资产却不可能全部以现金支付，存货也不可能全部售完。 6. 这个说法是可以接受的。因为某一个项目可以用权益来融资，另一个项目可以用债务来融资，而公司的总资本结构不会发生变化。根据MM 定理，融资成本与项目的增量现金流量分析无关。 7. ECA 方法在分析具有不同生命周期的互斥项目的情况下比较适应，这是因为ECA 方法可以使得互斥项目具有相同的生命周期，这样就可以进行比较。ECA 方法在假设项目现金流相同这一点与现实生活不符，它忽略了通货膨胀率以及不断变更的经济环境。 8. 折旧是非付现费用，但它可以在收入项目中减免赋税，这样折旧将使得实际现金流出的赋税减少一定额度，并以此影响项目现金流，因此，折旧减免赋税的效应应该被归为总的增量税后现金流。 9. 应考虑两个方面：第一个是侵蚀效应，新书是否会使得现有的教材销售额下降？第二个是竞争，是否其他出版商会进入市场并出版类似书籍？如果是的话，侵蚀效应将会降低。出版商的主要需要考虑出版新书带来的协同效应是否大于侵蚀效应，如果大于，则应该出版新书，反之，则放弃。 10. 当然应该考虑，是否会对保时捷的品牌效应产生破坏是公司应该考虑到的。如果品牌效应被破坏，汽车销量将受到一定影响。 11. 保时捷可能有更低的边际成本或是好的市场营销。当然，也有可能是一个决策失误。 12. 保时捷将会意识到随着越来越多产品投入市场，竞争越来越激烈，过高的利润会减少。

等式为：ROE=销售利润率×总资产周转率×权益乘数。可以看到净资产收益率（ROE）反映所有者投入资金的获利能力，反映企业筹资、投资、资产运营等活动的效率，是一个综合性最强的财务比率，所以净资产收益率是杜邦分析体系的核心指标。 3．影响企业短期偿债能力的最根本原因是（）。（浙江财经学院2011金融硕士）A．企业的资产结构 B．企业的融资结构 C．企业的权益结构 D．企业的经营业绩 【答案】D 【解析】短期偿债能力比率是一组旨在提供企业流动性信息的财务比率，有时也被称为流动性指标。它们主要关心企业短期内在不引起不适当压力的情况下支付账单的能力，因此，这些指标关注企业的流动资产和流动负债，但短期偿债能力比率的大小会因行业类型而不同，影响企业短期偿债能力的最根本原因还是企业的经营业绩。 4．市盈率是投资者用来衡量上市公司盈利能力的重要指标，关于市盈率的说法不正确的是（）。（浙江工商大学2011金融硕士） A．市盈率反映投资者对每股盈余所愿意支付的价格 B．市盈率越高表明人们对该股票的评价越高，所以进行股票投资时应该选择市盈率最高的股票 C．当每股盈余很小时，市盈率不说明任何问题 D．如果上市公司操纵利润，市盈率指标也就失去了意义

reported in the financing activity section of the accounting statement of cash flows. When Tyco received payments from customers, the cash inflows were reported as operating cash flows. Another method used by Tyco was to have acquired companies prepay operating expenses. In other words, the company acquired by Tyco would pay vendors for items not yet received. In one case, the payments totaled more than $50 million. When the acquired company was consolidated with Tyco, the prepayments reduced Tyco’s cash outflows, thus increasing the operating cash flows. Dynegy, the energy giant, was accused of engaging in a number of complex “round-trip trades.” The round-trip trades essentially involved the sale of natural resources to a counterparty, with the repurchase of the resources from the same party at the same price. In essence, Dynegy would sell an asset for $100, and immediately repurchase it from the buyer for $100. The problem arose with the treatment of the cash flows from the sale. Dynegy treated the cash from the sale of the asset as an operating cash flow, but classified the repurchase as an investing cash outflow. The total cash flows of the contracts traded by Dynegy in these round-trip trades totaled $300 million. Adelphia Communications was another company that apparently manipulated cash flows. In Adelphia’s case, the company capitalized the labor required to install cable. In other words, the company classified this labor expense as a fixed asset. While this practice is fairly common in the telecommunications industry, Adelphia capitalized a higher percentage of labor than is common. The effect of this classification was that the labor was treated as an investment cash flow, which increased the operating cash flow. In each of these examples, the companies were trying to boost operating cash flows by shifting cash flows to a different heading. The important thing to notice is that these movements don’t affect the total cash flow of the firm, which is why we recommend focusing on this number, not just operating cash flow. Summary and Conclusions Besides introducing you to corporate accounting, the purpose of this chapter has been to teach you how to determine cash flow from the accounting statements of a typical company. 1. Cash flow is generated by the firm and paid to creditors and shareholders. It can be classified as: 1. Cash flow from operations. 2. Cash flow from changes in fixed assets. 3. Cash flow from changes in working capital. 2. Calculations of cash flow are not difficult, but they require care and particular attention to detail in properly accounting for noncash expenses such as depreciation and deferred taxes. It is especially important that you do not confuse cash flow with changes in net working capital and net income. Concept Questions 1. Liquidity True or false: All assets are liquid at some price. Explain. 2. Accounting and Cash Flows Why might the revenue and cost figures shown on a standard income statement not represent the actual cash inflows and outflows that occurred during a period? 3. Accounting Statement of Cash Flows Looking at the accounting statement of cash flows, what does the bottom line number mean? How useful is this number for analyzing a company? 4. Cash Flows How do financial cash flows and the accounting statement of cash flows differ? Which is more useful for analyzing a company? 5. Book Values versus Market Values Under standard accounting rules, it is possible for a
